Problems solved by technology
For example: 1. There is an open arc structure on the plastic part. When the open arc structure is not supported by a metal insert inside, shrinkage will occur after molding
2. The positioning of metal inserts is not accurate or firm, resulting in uneven injection molding of plastic-coated gold products, and plastic parts are displaced or deformed

The invention relates to the field of injection molding. An anti-deformation injection mold for plastic-coated gold products, including a mold body for producing plastic-coated gold products, the plastic-coated gold products are composed of metal inserts and plastic parts; the mold body is provided with a supporting surface for supporting and positioning the metal inserts , the support surface is provided with a cavity for injection molding plastic parts; the plastic part is provided with an open arc structure, and there is no metal insert embedded support at the open arc structure; the cavity is provided with an opening arc structure for injection molding Arc cavity, the volume of the arc cavity is larger than the volume of the open arc structure, the part of the arc cavity exceeding the open arc structure is used as the deformation compensation space; the deformation compensation space is located at the opening of the arc cavity. In this patent, a deformation compensation space is set on the mold, so that the opening arc structure can be better approached to the drawing after molding and shrinking, so as to ensure that the product installation is no problem, and then meet the performance requirements of the communication filter unit.
Description
technical field [0001] The invention relates to the field of injection molding, in particular to molds. Background technique [0002] Many plastic parts with metal inserts will be deformed during injection molding. For example: 1. There is an open arc structure on the plastic part. When the open arc structure is not supported by a metal insert inside, shrinkage will occur after molding. 2. The positioning of metal inserts is inaccurate or not firm, resulting in uneven injection molding of plastic-coated gold products, and plastic parts are displaced or deformed. Contents of the invention [0003] The object of the present invention is to provide an anti-deformation injection mold for plastic-coated gold products to solve at least one of the above problems. [0004] An anti-deformation injection mold for plastic-coated gold products, including a mold body for producing plastic-coated gold products, the plastic-coated gold products are composed of metal inserts and plastic...
